| 中文摘要: |
| 在自行建造的人工湿地中试系统上,通过对化工尾水的实际处理试验,获得较好的处理效果,-些特征污染物经处理后,能达到规定排放标准,并分析了水力停留时间对人工湿地中COD,BOD,NH4+ - N,TP,Cu,挥发酚和AOCl等去除效果的影响及其规律,探明了各自的净化机理,试验结果表明人工湿地系统处理化工尾水方法可行;工艺参数建议水力停留时间以4 d为宜,进水COD负荷小于42.8 kg·(10-4m-2d-1).相关运行参数为人工湿地技术的-步发展及其工程设计与运行管理提供了参考. |

| Based on the model of constructed wetland,the treatment experiments on effluent of chemical sewage plant were done.High removal rates of contaminations were obtained.Some characteristic contaminations decreased to the discharge standard.The influence and regularity of hydraulic retention time on constructed wetland’s COD,BOD,NH4+-N,TP,Cu,Volatile Phenol and AOCl removal effect are analyzed in detail.And purification mechanism is explored.The results show it is an accessible way to treat chemical sewage effluent by constructed wetland.It is shown that the optimal running conditions with hydraulic residence time of 4 d,with COD loading rate of 42.8 kg·(10-4m-2d-1)was determined.Meanwhile,the optimal parameters of different operation condition are proposed so as to provide references for further development,design and operation of constructed wetland. |
